As far as symptoms, a bad battery in an iPhone 5c could produce overheating issues, sporadic shutdowns, and dismal battery life. Regardless what issue you're experiencing, we can walk you through start to finish!

How to replace the battery in an iPhone 5

Even though the iPhone 5 features a much larger battery than previous models, it's also powering the pixels to a larger screen. Since the iPhone 5 is now more than a year old, many owners may be seeing shorter than expected charge cycles that could warrant a replacement. Unfortunately, the iPhone 5 also seems to be more susceptible to faulty batteries. The most common issue seems to be users reporting when their iPhone 5 falls below 20% or so, it turns off and won't turn back on until plugged into a charger. This issue however, shouldn't be confused with a burnt out IC chip due to using a faulty charger. But if you're sure your battery is just bad, we can walk you through each and every step of replacing it, along with links on where to buy a new one.

The iPhone 3G and iPhone 3GS are well past showing their age but that doesn't make them disposable phones for many folks, at least not yet. At this point, most people probably have one or the other laying around that has less than stellar battery life. Perhaps you use it as a standby phone or iPod or you'd like to give it to a friend, relative, or child. Regardless the reason, a battery replacement can bring new life to both the iPhone 3G and iPhone 3GS. While a replacement involves quite a few more screws than other iPhone models, it's certainly doable for anyone mildly skilled with DIY repair. If you're willing to take the time and have just a few ninja moves up your sleeve, it's a super cheap repair to perform and may be worth it simply to have a spare phone laying around.

Good article. My IPhone 5 qualified for the replacement battery program. Took it to my local Apple store. The necessary diagnostics were run and failed. New battery replaced and diagnostics failed again. Instead of shipping my phone out I got a new replacement.

Can you recommend other suppliers? eTech shipping charges are nearly as much as the parts when purchasing 1-2 parts. Amazon has lots of vendors, and (since it's Amazon) MUCH better shipping rates. If they claim "OEM", can it be trusted? Thanks.

I only recommend what I've personally had experience with. I use eTech because they have very low failure rates, quality parts, and stellar customer service. I'd rather pay more for that than save a few bucks and potentially damage a device. I'm sure there are others that are ok but there are lots that aren't. I just won't recommend anything I don't have experience with personally.

How do you know you're getting an OEM battery if youre buying it from ebay or something. I mean yeah they may say it is OEM. safest thing to do is take it to Apple and have them replace it. If you have a iPhone 5 then search "Apple battery replacement program" and the first link will tell you whether you can get a free battery or not.
